Bauer Sindorf – further models: the collective page for trailers outside the named series, ATU3-34S and ATU4-40S, 7,800 to 11,300 kg unladen weight, 40,000 to 44,000 kg gross weight
This page collects the Bauer Sindorf trailers that the register does not assign to any named series. Two types are listed: ATU3-34S and ATU4-40S. Both stand in the register as separate entries, and the designations themselves give no indication of a series logic.

The register lists 2 versions here with unladen weights from 7,800 to 11,300 kg, gross weights from 40,000 to 44,000 kg, lengths from 10,850 to 14,300 mm and a width of 2,500 mm.
With gross weights from 40,000 to 44,000 kg, this range sits above the usual 40-tonne limit for road haulage and falls into EU trailer category O4 with mandatory air brakes; journeys above 40 tonnes require an exceptional heavy-haulage permit in most European countries. The low unladen weight relative to the gross weight points to a bare load-bearing structure without a fixed body, typical of module carriers or axle trailers designed for varying loads.
With gross weights of 40 to 44 tonnes against a comparatively low unladen weight, these trailers belong to the heavy axle-trailer or module-carrier class used in heavy-goods haulage behind specialist tractor units; the large ratio of payload to unladen weight is typical for this design.
When buying used in this class, check in particular the condition of the axles and air suspension, the operation of the air braking system including ABS/EBS, cracks in the chassis and side members, and corrosion on load-bearing parts. Spare parts for such heavy trailers usually come through specialist commercial-vehicle and semi-trailer workshops rather than a manufacturer network.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
